	Curved crystals have been successfully used for a long time on the proton synchrotron U-70 of IHEP for the extraction of high-energy proton beams. With the beginning of the program for accelerating carbon ions at the U-70, crystalline deflectors of different lengths and different bending angles have also found application to provide experimental physical installations with ion beams. The report overviews recent results of activity in implementing crystal deflectors to extract proton and ion beams for the fixed-target experiments at the U-70 synchrotron of IHEP of National Research Centre "Kurchatov Institute".

	The U-70 NRC "KI" - IHEP ring magnet made-up of combined functions, this magnet used to steer and focus a beam simultaneously. The existing commercial power supply with pulse-width modulation (PWM) voltage was not suitable because of electromagnetic incompatibility. The problem of suppressing 100% output voltage ripples by about minus 60 dB, was solved. It is planned to use the upgraded source to deaccelerate the beam of light ions in the U-70 synchrotron. The goal is to increase the energy range of the ejection beams to physical, medical, etc. researches.

Results of the fast wire scanner approbation for determination of transverse injection errors and evaluating transverse feedback efficiency are presented.

The carbon ion beam extraction scheme from the U-70 synchrotron of NRC "Kurchatov institute" - IHEP for radiobiological researches is presented. The double-step extraction scheme Piccioni-Wright is used. The beam extraction operates at magnetic field flat bottom of U-70 synchrotron with carbon ion energy 455 MeV/n. A technique to attain transversally uniform dose field and other operational results are also presented.

Results of experimental study of the transverse beams size in the U70 synchrotron based on a fast wire scanner are given. Measurements of the transverse beam size were carried out at three special points of the U-70 synchrotron magnetic cycle: on the injection flat top (1.3 GeV proton, 0.455 GeV/u carbon); in the region of the transition energy (7.959 GeV proton); on the main flat top (49 GeV proton). Results of the fast wire scanner approbation for determination of transverse injection errors and evaluating transverse feedback efficiency are presented.
